Anti-kink for oxygen hose

I created this I when worked for an oxygen company. When a humidifier sets on top of a concentrator, the hose goes from the top of the bottle to the front of the machine. Over time, the hose gets a kink in it because it is going straight up out of the bottle and the connection it's going to is below it. This just slides on the hose at the top of the humidity bottle. No more kinks
